Wow! It has been a long time since my last tutorial… As I wrote in my last post, I had to take a break due to my wife having our baby. But, now I’m back and have a great tutorial for you guys. Today I will be showing you how to work with a UIWebview to create a basic web browser. Here is a screenshot of the app we are going to create. Create a View-Based Application Ok, so let’s get started. Start

In this tutorial, I will be showing you how to use UITouch to get the location of where a user touches on the screen. We will be using this knowledge to drag a UIImageView around. Learning how to use UITouch is the first steps in creating applications that are not navigation based (or don’t only use Apple’s built in components. Later on, we will begin some basic game development that will utilize

In this tutorial, I will be showing you how you can save and retrieve different types of data using the NSUserDefaults object. Saving this way is great for when you want to save small amounts of data such as High Scores, Login Information, and program state. Saving to the NSUserDefaults is great because it does not require any special database knowledge. So if you don’t want/have an SQLite3 databa

I have noticed recently many people wanting to create games for the iPhone and are unsure where to start. A common misconception is that you must use OpenGL ES to create any game with graphics. I am going to show you today how you can do some simple animation by moving a ball around the screen. We will not be using OpenGL ES to move the ball. We will simply be using an NSTimer and a UIImageView. T

This tutorial is part 2 in our series of creating a to-do list. I will assume that you have completed the following tutorial and its prequisites. iPhone Programming Tutorial – Creating a ToDo List Using SQLite Part 1 I will be using the code produced from that tutorial as a base for this one. When you are finished with this tutorial, your application will look something like this: In this section,

In this tutorial I will show you how to develop a UITabBarController which contains a custom UIView from one of the tabs and a UINavigationController with a UITableView dictated byUISegmentControl in the second tab. This tutorial was contributed by the user . You can check out his website at If you would like to contribute a tutorial to iCodeBlog.com, contact me The final product of this tutorial

This tutorial will show you the basics of using the UITabBar and UITabBarItem controls when programming for the iPhone. I will be showing you step by step in the video how to create a project from a UITabBar template and add additional UITabBarItems as well as additonal views to be displayed with these items. Here is a brief explanation of each step: 1. Create a new project from a UITabBar templat

In this tutorial I will walk to you through creating a simple “Hello World” application using a UITableView for the iPhone. There are many ways that a Hello World program could be made on the iPhone, I am going to show you the simplest. This tutorial assumes you have a basic understanding of Objective-C. Apple has provided a very simple and straight forward tutorial on Objective-C. You can find it

This tutorial will focus on transitioning from one view to another. We will be utilizing Apple’s UINavigationController. I will be using the code from the “Hello World” tutorial that I previously wrote. So if you have not completed it yet, go ahead and do it and come back to this page. (It’s quick I promise). You can view it here. In this tutorial you will learn: Add A New View Add A View Controll

If you have been following my tutorials, you know that we have been working primarily with UITableViews. This is mostly because SO many applications can be developed using this simple control. This final UITableView tutorial will be taking all of the skills learned from previous tutorials, putting them all together, and adding SQLite to create a prioritized To-Do list. I will also be showing you h

Finally, we get to write some real code! In this tutorial, I will show you how to create an interface using Interface Builder and connect it to your code. We will be creating a UITextField, UILabel, and a Button. Now, don’t be intimidated that this tutorial is so long. I have really went into detail explaining everything as I go. You could easily scan over it and get the gist of it. Here’s how the

The goal of this tutorial is to show you how to populate a UITableView with data from an array of objects. This will be the building block to display XML data as well as SQL data. The theme of this application will be fruit. We will create an array of “fruit” objects that have some additional information besides the name. We will populate a UITableView with the names of the fruits. When the user s

I was recently working on an internal project for Burnside Digital, and decided it was time to do some memory profiling to make sure that I didn’t have any leaks. I ran the program with the ‘Leaks’ tool of instruments, and as I was watching the Live Bytes column, I saw the number of Bytes being used, slowly but surely increasing as time went on. Instruments wasn’t detecting any leaks, so I knew th
